| Tóm tắt: | Since the publication of the first edition of this book in 2001, there have been several sig-
nificant developments in forestry and forest entomology in the tropics that warranted
inclusion in a second edition. One is the emergence of new pest species associated either
with the expansion of plantation forestry into new regions or marginal areas, or a gradual
adaptation by indigenous species to exotic hosts or the rapid spread of new invasives. The
South American carpenterworm, Chilecomadia valdiviana, in Chile, and the South African
goat moth, Coryphodema tristis, are examples of emerging indigenous pests associated
with the establishment and expansion of exotic Eucalyptus spp. plantations in these coun-
tries. The blue gum chalcid, Leptocybe invasa, and the erythrina gall wasp, Quadrastichus
erythrinae, are recent examples of the rapid worldwide spread of an invasive insect, similar
to that which occurred for the leucaena psyllid, Heteropsylla cubana, in the 1980s and
1990s. The biology, ecology and impact of these, and many additional pest species, are
discussed in an expanded Chapter 5.
Another development has been the growing awareness of the 'true' global impact of
forest invasive species as losses have been better quantified. Damage worldwide has been
estimated at several billion US dollars per year, even without taking into account the loss
of non-market value, which may well exceed that figure. This has prompted a range of
international responses, including the formation of networks and surveillance programmes
to provide early warning of incursions of forest invasives and the development of interna-
tional standards for phytosanitary measures, such as that for wood packaging material, as
discussed in Chapter 9. The global increase in self-help schemes such as plant clinics and
field schools is also discussed. A range of new technologies has enhanced the accuracy and
efficiency of forest health surveys over the past decade. These include the use of geographic
information system-global positioning system interface tools and handheld computers to
assist navigation and data collection in the field, and the application of digital, remotely
sensed imagery to detect and classify damaged forest canopies. There have also been signifi-
cant advances in the use of semiochemicals, including pheromones, for the detection and
monitoring of forest pests and for controlling pest populations by means of mass trapping,
lure and kill, lure and infect and mating disruption. |
